T 0 all whom it may concern:

Be it known that I, PATRICK JOSEPH COLE- MAN, a citizen of the United States, residing at Bristol, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Radi 'ator Heating Systems, of which the followin is aspecification.

y invention relates to improvements in radiator heating systems, involvingthe use of a radiator of the form that is adapted for use in heating households and apartments by means of steam, and the object of my improvement is to incorporate in the i system comprising the boiler and the radiator means that are applied to the radiator, in the form of a siphon structure, whereby the manner of operation and use of the radiator can be changed at will so as to operate in one setting or position of adjustment strictly as a steam radiator in substantially the ordinary manner and in another setting will be adapted to retain the condensation in the radiator up to a certain height, which may be two thirds the height of the radiator, so that the operation as a steam device will be confined to the portion that is above the level of the water of condensation, and, furthermore, in order to relieve the boiler and prevent flooding in case the accumulation of water from one or more radiators is released by opening the discharge valve or V valves, I provide a receiver that is' connected in a proper manner with the boiler and the piping system.

In the accompanying drawing Figure 1 is a diagrammatic view of my improved radiator heating system, showing a single radiator, a boiler, a receiver, a siphon device, and the proper connections and valves.

Fig. 2 is a front elevation of a radiator and a siphon device, with the proper connections for operation in accordance with my improved system.

Fig. 3 is an end elevation of the radiator and siphon device shown in Fig. 2,

My improved radiator heating system comprises in combination, a radiator 10, a siphon device 11 positioned preferably adj acent one end thereof, a boiler 12 positioned below the radiator and siphon device, a receiver 13 positioned adjacent the boiler, and suitable connections and valves.

The radiator 10 is substantially of the usual form that is used for heating by means of steam, comprising a plurality of tubular upright members 14: that terminate at their upper ends in the top header or manifold 15 and at their lower ends in the bottom header or manifold 16.

The steam inlet is at the top, at the top header 15, which is connected with the main steam supply pipe 17 that comes from the boiler 12, and which'is provided with a control valve 18 adjacent the header 15.

The discharge is from the bottom header 16, by means of the laterally directed pipe 19, which is connected through devices to be described to the main discharge pipe 20 that connects with the boiler 12.

The receiver 13 is positioned adjacent the boiler 12 and is connected adjacent its lower end by means of a pipe 21 with the boiler 12. As shown, the main discharge pipe 20 connects with the pipe 21 between the receiver and the boiler, so that the liquid discharge may flow into the receiver and the boiler to the common level.

An equalizer pipe 22 may be used to interconnect the upper ends of the boiler 12 and the receiver 13.

The main discharge pipe 20 is provided with a control valve 23, positioned to one side of the devices mentioned.

The said devices comprise as one part the connection 24; of U-shape that is intermediate the radiator discharge outlet 19 and the main discharge pipe 20 and is provided with a control valve 25, and which corresponds operatively t0 the ordinary structure used for the discharge from a steam radiator.

Incorporated with the said one part is a second part in the form of the siphon de vice 11.

The said siphon device 11 comprises one branch 26 that is in the form of an upward extension of the main discharge pipe 20, a second branch 27 that connects with the radiator discharge pipe 19, being intermediate the radiator 10 and the radiator discharge valve 25, and the connecting art 28 that interconnects the said branc cs 26 and 27.

The part 28 or upper end of the siphon device 11 is positioned at an appreciable elevation relatively to the radiator, being in some cases for satisfactory operation as high as two-thirdsthe height of the radiator.

venient andefiective manner, for use in rel atively moderate weather. a

The operation of this feature is as follows:-By closing the radiator discharge valve 25 the steam condensation will accumulate in the bott'om of the radiator 10 and will serve to displace steam accordingly,

the steam being confined to the upper part.

The limit of this condition 'is. reached when the accumulation has reached the heightof the turn 28 in the upperpart: of thesiphon device 11, when the discharge will overflow into the main discharge pipe 20.

By opening the discharge valve 25 the accumulated condensation will be admitted at once to the main discharge, pipe 20. In

such case the receiver 13 serves to prevent;

a rush of a surplusageof waterto theboiler,

.;and thereby serves to relieve the boiler in holding water, thus permitting of a relatively large number of radiators being operated int-he one system. The control valves mentioned, 18,23, and 25' are all. operatively similar, ,and of ordinary form, each being. a simple, one-way valve, suchas may be designated briefly as a shut-off valve.

The method of operating household radiators described may be used also in connection with systems-inwhich-steam is supplied for heating purposes from a central supply plied from a locally installed boiler, the

siphon device being provided in combination with the radiator, substantially as described. I; claim as my invention Inca radiator heatmgjsystem, in combination, a radiator-having; a discharge outlet at the lower end,- a siphonstructure positioned alongside the. said' radiator a direct 'dis-. charge pipe connected to the said discharge outlet, a shutpfl valve positionedintermediate thelends otthe said pipe for permitting tothe said pipe, one on each side ofthefsaid valve, whereby by closing the said valve the discharge from the: radiator will be directed,

indirectly byway of the said? siphon structure,and the said arms being ot appreciable length and directed upwardly relatively to the saidpipe, so that condensation in the siphon structure will serve as a trap to retain condensation in the radiator. a i
